3 Overview
The Kramer WP-120 wall plate is an XGA line receiver that receives an
encoded CAT5 signal transmitted by a transmitter
4
, decodes it and converts it to
an XGA output. In particular, the WP-120:
Includes EQ. and level controls
Has the power connect feature
5
Is 12VDC fed

3.1 About the Power Connect Feature
The Power Connect feature applies as long as the cable can carry power. The
distance does not exceed 50 meters on standard CAT5 cable. For longer
distances, heavy gauge cable should be used
1
.
For a CAT5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
It is recommended that in applications with high interference, shielded twisted
pair (STP) cable is used. However, the shield itself does create a capacitance
that degrades the frequency response of the machines. For shorter distances, of
50m or so, shielded twisted pair (STP) cable is preferred because it provides
protection from interference (degradation is not apparent).
For long range applications, unshielded twisted pair (UTP) cable is preferred.
However, the unshielded twisted pair (UTP) cable should be installed far away
from electric cables, motors and so on, which are prone to create electrical
interference.
3.3 Recommendations for Achieving the Best Performance
Achieving the best performance means:
Connecting only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
Avoiding interference from neighboring electrical appliances and
positioning your WP-120 away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
2
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 CAT5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

4.3 Installing the WP-120 XGA Line Transmitter
To install your WP-120 XGA Line Transmitter:
1. Connect the line out RJ-45 connector of the transmitter to the pre-installed
UTP wiring in the wall box opening that connects via UTP cabling to the
LINE IN RJ-45 connector of the WP-120.
2. Connect your 12V DC power supply to the POWER SUPPLY pins
1
,
taking care that polarity is correct.
3. Insert the WP-120 directly into the wall box opening, and then mount the
front panel securely using the screws.
4. Connect the XGA acceptor to the XGA OUT HD15F connector.
